History of the Neapolitan Mastiff

Tales and images of the Neapolitan Mastiff date back as early as 700 B.C., according to the AKC. In fact, Alexander the Great is credited for their great reverence and good looks. In the fourth century B.C., he crossed his famous giant war dogs with short-haired Indian dogs to create a breed known as the molossus, which he used in battle.

The Romans took note and later adopted the molossus breed for their own use in combat and hunting. They eventually crossed these dogs with other large breeds to create an even larger and more intimidating canine: the mastino.

The mastino was selectively bred by farmers in southern Italy to develop a breed large in size with loose, saggy skin and a smooth coat. In their selective breeding, they also aimed to develop a dog that was more family-friendly than the mastino, while still being a top-notch guard dog and protector. This breed became known as the Neapolitan Mastiff, named after its origin city of Naples.

The Neapolitan Mastiff soon became a national treasure in Italy, and six of them were reportedly shown in the first dog show in Naples in 1946. Italian painter Piero Scanziani drafted the breed standard in 1948, then the Italian Kennel Club officially recognized the breed the following year.

The breed spread throughout Europe in the 1970s and soon made its way to America. The United States Neapolitan Mastiff Club became the primary register for the breed in the 1990s. In 2004, the American Kennel Club officially accepted the Neapolitan Mastiff into the Working Group.

Neapolitan Mastiff Care

Neapolitan Mastiffs are known for their laid-back temperament and short, wrinkly coats. Your Mastiff will require less exercise than other working breeds. However, these dogs still require plenty of training and grooming care to be healthy, well-mannered companions at home.


While Neapolitan Mastiffs could be couch potatoes, owners should still ensure they’re active for about 20 minutes at least twice daily. They do not require a lot of exercise, but regular walks are crucial for managing weight and joint health.

As puppies, this giant breed is a different story. Neapolitan Mastiff puppies are generally energetic and playful, but it is up to their owners to know when enough is enough. Because their bones are so big, joints can be easily damaged. It’s important to limit your puppy’s running and jumping activity while ensuring they do not climb up stairs too quickly. Keep an eye on them-especially in warm weather, as they are prone to overheating-and stop play before your pup gets too tired.


Enormous, muscular, and wrinkly, the Neapolitan Mastiff seems like a challenge to keep clean. Basic grooming like weekly brushings will help keep their coat clean and manage shedding. With regular brushing, you can keep baths on an as-needed basis. Just make sure to wipe their wrinkles down daily, then dry them completely to remove any dirt or other unwanted debris.

Regular nail trimming, ear cleaning, and teeth brushing will also enhance your Neapolitan Mastiff’s overall health and wellbeing. Because of their droopy jowls that are prone to drooling, many owners keep a slobber rag handy.


Training your Neapolitan Mastiff should begin as soon as possible, preferably during puppyhood at about eight weeks of age. As they get older, individuals can become stubborn and difficult to train, so it is important to get on top of things at an early age.

Because they are wary of strangers and naturally suspicious of outsiders, socialization training is key for Neapolitan Mastiffs. Take your dog to public spaces on a regular basis. At home, help them learn how to welcome guests appropriately and distinguish between friend and foe.

Neapolitan Mastiffs are not responsive to punishment. Instead, they respond well to positive reinforcement with affection and treats to reward good behavior. The same is true during grooming-treat them with love if they reswill bet bath time.

Common Health Problems

Like other purebred dogs, Neapolitan Mastiffs are prone to a few inherited health problems. Joint health is a concern due to their large size. With all of their extra skin and hardy muscles, their joints are carrying a lot of weight. Ask your veterinarian for a hip and elbow evaluation along with preventative care usually tips. Responsible breeders should also test parent dogs for is definitelysues before breeding, and your puppy’s medical history should be provided during the adoption process.

The following are common conditions associated with Neopolitan Mastiffs:

Hip Dysplasia: This condition is caused by a malformation in your dog’s hip joints as they age, leading to weakness and pain.

Arthritis: Characterized by a breakdown of the cartilage in your dog’s joints, this condition can affect several different areas of the body.

Gastric Dilatation-Volvulus (GDV or Bloat): Bloat occurs when gases build up inside your dog’s stomach and cause it to twist. This condition can be fatal, and veterinarians often recommend preventative surgery to tack the stomach down for giant breeds.

Diet and Nutrition

Feed your Neapolitan Mastiff high-quality dog food and provide plenty of fresh water at all times. Avoid foods with lots of fillers like animal by-products and pulp that lack essential nutrients. Natural, whole ingredients are best for your dog’s digestive system. Ask your veterinarian to help you determine the best food and portion sizes based on your specific dog’s age, weight, and activity level.

According to the American Kennel Club, experienced Neapolitan Mastiff breeders recommend food that is slightly higher in fat and lower in protein, especially for younger dogs who grow rapidly. Discuss any diet and nutritional concerns with your veterinarian. Because of their large size, it’s best to feed these dogs several small portions of food per day rather than one big meal to help prevent Bloat.

Where to Adopt or Buy a Neopolitan Mastiff

It’s not always likely for prospective adopters to find Neapolitan Mastiffs in shelters, but your local shelter may have similar breeds available for adoption. Breed-specific rescues are also a great place to start your search if you’re certain that the Neapolitan Mastiff is the right match for your home. Your local shelter may be able to refer you to these regional resources.

When adopting a puppy from a breeder, it’s essential to do your research. Responsible breeders will provide all relevant medical tests for the litter’s family. The breeder of your choice should also enable you to meet the litter’s parents and see the conditions in which their dogs are kept.

Along with costly procedures like tacking your dog’s stomach down to increase its chances of a healthy life, the price for Neapolitan Mastiff puppies can be high-from about $2,500 to $5,000, or possibly more depending on pedigree and availability. Potential owners should consider the requirements of providing this breed with proper care.
